Hi,
I’ve flashed two esp32 as Bluetooth-Proxys and they connected to my four Govee H5705 successfully.
The one without the connection problems at the bottom is standing next to the raspi and is connected via its bluetooth.
I’ve read several topics and looked into the docs, but can’t seem to find the problem.
Does anyone has an idea how this can be fixed? I’ve played with the interval, duration, etc a bit, but it doesn’t seem to help.

It seems I misjudged how bad the internal esp32 antenna really is. Soldering antennas to each one helped immensely.
If you’ve purchased an ESP board without a connector for an external antenna and find you are pushing the limits of reception - all is not lost.
Also this is slightly easier than moving the 0603 sized resistor required to use the external antenna socket on some boards.
These parts can be found for a couple of dollars on ebay or Aliexpress:

Good to go:

I hope this can help someone in the future.

I have the same problem but I don’t get how increasing your wifi connectivity helps with the loss of Bluetooth connections.
The same antenna is used for both WiFi and Bluetooth.
